What is a cheap tool that would work well at cutting a 2.5 inch

a saw and a router?
you have to do it in two steps. first route the half moon part with a router ( get some cheap router from harbour freight tools... literally like 15 dollars, ) and the router bit you need... could also be about 15 dollars, depending on where you but it

Holesaw should do the job, just use or find the size that matches your intended radius.

You need a descent drill for those. Low and cost ones usually don't have the torque.

So it takes OP 50 seconds instead of 30. Your point?

This. You'll never get a good semicircle eith a hand router unless you use them all day every day, and thats a lot of fucking around for a 10 second job. Just make sure your piece is on a second piece of timber so when the center drill goes through it has something to stay centered on.

Whats your mission OP?

2.5" thick with a router?
what kind of crazy oversized router bits do you have?

I thought the view was a lateral view. that's all.

you know what's crazier? 2.5in plywood, that's what's crazy. do they even make that?

I don't think so.
Thickest I ever bought was 1".
2.5 would be expensive as shit.

need a more accurate diagram with measurements, OP. I think everyone has got a different idea of what you're trying to do. post the same diagram with measurements, please.

Saw the middle
Rasp the end?

This. Remember to periodically let the sawdust out, though, it'll just sit in the groove and heat up otherwise.

it's plywood, not MDF.

MDF catches on fire with a router... I learned that the hard way.
